If the yellow INTERLOCK LED is blinking:
1. Check the configuration for External Device Monitoring. If EDM is inactive
(via receiver dip switch), the input (pink wire) must be connected to system
ground. If EDM is active, the input must be connected to the normally
closed contacts of the control relays of the guarded machine or the monitor
terminal of the safety relay unit. Please refer to SECTION 11 Connection
to the Machine Control Circuit for an example.
2. Make sure both selector switches in the receiver endcap have been set
properly and identically. Please refer to chapter 7-2 Operating mode selec-
tion for further information.
3. Verify the power supply is within the specified limits (+24V ±20%).
4. Verify the light curtain is properly connected to the control relays of the
guarded machine. If the light curtain is not intended to be connected to
control relays, see SECTION 12 Muting for further information.
5. Verify the control relays are within operating limits of the safety outputs.
6. Verify the cable lengths from the light curtain to the control relays are within
specified limits.
7. If this does not solve the problem, please contact your local Omron distrib-
utor or the European Repair Center.
